GSLV-F05/INSAT-3DR MISSION
[size=x-large]Launch Video of GSLV F05 INSAT-3DR [/size]
GSLV-F05
GSLV-F05 is the tenth flight of India's Geosynchronous Satellite Launch Vehicle (GSLV). In this flight, GSLV will launch 2211 kg INSAT-3DR, an advanced weather satellite into a Geostationary Transfer Orbit (GTO). After reaching GTO, INSAT-3DR will use its own propulsion system to reach its final geosynchronous orbital home and will be stationed at 74 deg East longitude. INSAT-3DR will provide a variety of meteorological services to the country. GSLV is designed to inject 2 - 2.5 ton class of satellites into GTO.
GSLV-F05 is the flight in which the indigenously developed Cryogenic Upper Stage (CUS) is being carried on-board for the fourth time during a GSLV flight. GSLV-F05 flight is significant since it is the first operational flight of GSLV carrying CUS. GSLV-F05 will be launched from the Second Launch Pad at Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota.
GSLV-F05 vehicle is configured with all its three stages including the CUS similar to the ones successfully flown during the previous GSLV-D5 and D6 missions in January 2014 and August 2015. GSLV-D5 and D6 successfully placed GSAT-14 and GSAT-6 satellites carried on-board in the intended GTOs very accurately.
GSLV-F05 / INSAT-3DR Mission is scheduled to be launched on Sept 08, 2016 at 16:10 hrs (IST) from SDSC, SHAR, Sriharikota.
INSAT-3DR
INSAT-3DR is an advanced meteorological satellite of India configured with an imaging System and an Atmospheric Sounder.
Three meteorological satellites of India - KALPANA-1, INSAT-3A and INSAT-3D - are operational in the geostationary orbit for the past one decade at 74, 93.5 and 82 degree East longitudes respectively. KALPANA-1 and INSAT-3A have imaging systems providing images in the Visible, Near-Infrared, Shortwave Infrared, Water Vapour and Thermal Infrared bands.
INSAT-3D, launched in 2013, added a new dimension to weather monitoring through its Atmospheric Sounding System, which provides vertical profiles of temperature (40 levels from surface to - 70 km), humidity (21 levels from surface to - 15 km) and integrated ozone from surface to top of the atmosphere. INSAT-3DR, the latest meteorological satellite built by ISRO, is similar to INSAT-3D.
The significant improvements incorporated in INSAT-3D compared to the earlier meteorological missions are part of INSAT-3DR also. These are:
Imaging in Middle Infrared band to provide night time pictures of low clouds and fog
Imaging in two Thermal Infrared bands for estimation of Sea Surface Temperature (SST) with better accuracy
Higher Spatial Resolution in the Visible and Thermal Infrared bands
And, like its predecessor INSAT-3D, INSAT-3DR carries a Data Relay Transponder as well as a Search and Rescue Transponder. Thus, INSAT-3DR will provide service continuity to earlier meteorological missions of ISRO and further augment the capability to provide various meteorological as well as search and rescue services.
INSAT-3DR has a lift-off mass of 2211 kg, which includes about 1255 kg of propellant. The propellant carried by INSAT-3DR is mainly required to raise the satellite from the Geosynchronous Transfer Orbit (GTO) to its final Geostationary Orbit and to maintain the satellite in its orbital slot during its life. INSAT-3DR is based on ISRO's two Tonne Class platform (I-2K bus) employing light-weight structural elements like Carbon Fibre Reinforced Plastic (CFRP). The satellite has a solar array generating 1700 Watts of power.
